BASE PLATE AND FILLER BLOCK FOR SWITCH POINTS.

Application filed August 10, 1927. Serial No. 212,078.

This invention relates to switch points and aims to provide novel means whereby the;

blocks being provided with openings to rerails of a switch may be securely held together against lateral movement, but will be permitted to move longitudinally, independently of each other.

Another ob 'ect of the invention is to provide a filler block having countersunk bolt openin s, so that the heads of the bolts employed for connecting the filler block to the switch rail, will be embedded in the filler block, to the end that all possibility of the bolts restricting movement of one rail with respect to another, will be obviated.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is a plan view illustrating the application of the device forming the subject matter of the present invention.

Figure 2 is an enlarged detail view illustrating the filler block and base plate.

' Figure 3 is a transverse sectional view through the rails, filler block and base plate.

Referring to the drawing in detail, the reference character 5 designates the rails of a railway track that intersect the rails 6 of the adjacent track, the tracks being connected at the switch points 7.

The device forming the subject matter of this invention includes a securing device, and as shown, the adjacent rails of the tracks are connected through the medium of these securing devices in such a way that the rails will be held against lateral movement, but will be permitted to move slightly longitudi-' nally with respect to each other under the action of heat and cold. As shown, each securing device includes a base plate 8 having upstanding flanges 9 and 10 respectively, the flange 10 being longer than the flange 9 so that the same will contact with the under surface of the ball 11 of one of the rails of the switch.

Positioned between the adjacent rails of the switch are filler blocks 12, the filler ceive the bolts 13, the openings being countersunk to completely house the heads 1 1 of the bolts, thereby insuring against any pos sibility of the heads damaging the rails, should the rails move slightly longitudinally with respect to each other when they expand or contract.

, These bolts also extend through openings in one of the rail webs as shown by Figure 3, from where they pass through the plate 15, the plate acting as a splice bar at the adjacent ends of the rails.

Nuts 16 are provided on the bolts 18 and when tightened move the filler block, plate 15 and rail into close engagement with each other.

The flange also contacts with the nuts 16 to lock the nuts 16 against movement under the vibration of the rails of the track, when a train is passing thereover. Spike openings are also formed in the base plate to receive the spikes 17 for securing the base plate in position. Thus it will be seen that due to this construction the rails may move longitudinally through the base plate, independently of each other, the base plate acting to hold the rails against lateral and vertical movement.

I claim A device of the class described comprising in combination, a rail chair having upstanding flanges, a pair of rails arranged in spaced parallel relation with each other and resting on the chair and held between the flanges, a filler block between the rails to hold the rails in proper spaced relation with each other. said filler block having countersunk bolt openings registering with openings of one of the rails to secure one of the rails to the filler block, to permit movement of one rail and filler block independently of the other rail, and means for securing the chair to rail supporting ties.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.

ROBERT WILLIAM WAITS.
